The Attempt at a Solution
Because two base angles in a congruent triangle are the same and I have been given one of them I did the following:
3x+5 = 3x+5 (I then tried to solve for x but this cancels out to 0.)
I want to know why this is the case, i think it is because i have 2 unknown variables but only1 equation.
